The genus Pleurotus in Argentina

Area of Science:

• Mycology
• Botany
• Fungal Taxonomy

Background:

• The genus Pleurotus is globally recognized for its edible and medicinal properties.
• Accurate identification of fungal species is crucial for both ecological and economic purposes.
• Previous taxonomic studies on Pleurotus in Argentina were limited, necessitating a comprehensive review.

Purpose of the Study:

• To conduct a detailed taxonomic analysis of the genus Pleurotus in Argentina.
• To identify and describe the species of Pleurotus present in the region.
• To provide an updated checklist of Pleurotus species and their varieties found in Argentina.

Main Methods:

• Macro- and micromorphological characterization of Pleurotus specimens from field collections and national herbaria.
• Utilizing cultivation techniques to produce and study fresh basidiomata (fruit bodies).
• Comparative analysis of morphological data to distinguish between species and varieties.

Main Results:

• Six species of Pleurotus were identified in Argentina: P. albidus, P. cystidiosus, P. ostreatus, P. pulmonarius, P. rickii, and P. djamor.
• The species P. djamor was further classified into three distinct varieties: var. djamor, var. cyathiformis, and var. roseus.
• Morphological data confirmed the presence and distinctiveness of these taxa within Argentina.

Conclusions:

• The study establishes the current diversity of the genus Pleurotus in Argentina, identifying six species and three varieties.
• This research provides a foundational taxonomic framework for future studies on Pleurotus in South America.
• The findings contribute to a better understanding of fungal biodiversity and taxonomy in the region.
